Application filed January 3 Specification of Letters Patent. Patented Aug. 29, 191] i 1,911. Serial No. 600,675.

To all whom it may concern:

Be it'known that 1', ROBERT G. CLYNE, a subject of the King of Great Britain, residing at Upper Alton, in the county of Madison and State of Illinois, have invented certain new and useful Improvements in Cartridges, of which. the following is a specification; I

This invention relates more especially to that class of cartridges commonly termed jectto provide improved means tor securing the shell to the cap;

A further object is toprovide improved means for anchoring the basewad in position Within the cap.

More specifically stated, the main object of the present invention is to provide an improved combined basewad anchor and cap reinforce by'means of which the cap and shell are inseparably connected while at the same time providing an improved. gas-tight joint between the base wad and the percussion cap.

Another object is to provide an improved device of this character which will permit assembled in manufacturing the shells.

Other andfurther objects will appear in the specification, and be specifically pointed out in the appended CliLlIIlS, reference being had to the accompanying sheet of drawings exemplifying the invention, and in which- 1 Figure 1 is a side elevation of a cartridge shell, partly broken away to show the interio roonstruction thereof. Fig.2 is a transverse section on the line II-II, Fig. 1. Fig. 3 is an axial section of the wad anchor or showing the method of constructing said anchor. Fig. 5 is a'perspective view of a fragmentary side elevation of a shell, partly broken away to show the application of the embodiment shown in Fig. 5. Fig. 7 is a side elevation partly broken away of a modition.

I Referring more particularly to the drawings, in which like reference characters refer to thesame parts wherever they occur,! the embodiment shown in Figs. 1 to 4, in'-.

with a head or base cap-2, which is secured to said paper shell in the improved manner to hereinafter referred to. The'head cap 2 18 provided with the usual peripheral flange 3 for holding'the cartridge injposit-ion within the breech of a gun barrel while the fiat end wall of said cap is provided with the usual central aperture formed by a hole punched therein for the reception of a -bat tery cup 4: of well known construction. Interposed between the battery cup 4 and the cylindrical wall of'the'cap 2 and extending around the former, is the base wad 5.

According to Figs. 3 and 4, theanchor is exemplified in an integral piece of sheet metal, which is first stamped as shown'in Fig. 4 to provide an outer cylindrical Wall 8, end wall 9 and a plurality of bailies or wings 10, said wings being preferably formed, as indicated in Fig. 4, by stamping in the end wall of the anchor a plurality of segmental slots 11 and radial slots 12 meeting at the center, the partially severed portions be tween said slots being then forced inwardly in the manner shown in Fig. 3 to form the wings 10 approximately diamond-shaped.

The wings 10 being circularly bent, their pointed ends adapt them to be inserted between contiguous folds of the base wad roll before it is compressed home into permanent position.

Referring again. to Fig. 1, the wings 10 being inserted into the base Wad 5 in the inanner indicated, and the shell 1, cap 2 and base wad 5 being assembled with the cylindrical wall 8 interposed between the inner cylindrical wall of the shell 1 and the cylindrical wall ofthe cap 2, the pressure to which the base wad is subjected to compress it, buckles the wings in a manner corresponding to the way in which the layers of the base wad are.

caused to flow under compression. It will be seen therefore that the anchor becomes securely interlocked with the compressed base wad by means of the crinkled wings 10. The base wad 5 is furthermore interlocked with said wings by reason of its flow under compression which forms a solid mass of the ;wad extending through the wedge-shaped spaces'undcr. the points of the wings. 10. When the arts are forced together, as ashown in Flg. l, the anchor has formed .thereon an annular shoulder 14 which fits within the recess formed within the flange 3 on the head cap 2. The anchor is, therefore,

positively interlocked with the head cap, and consequently very effectually locks the base wad to the cap 2. The anchor may be adapted .0 more positively engage the tubular shell 1 in various ways, one of these being illustrated in Figs. 5 and 6 and consisting in providing the outer wall with a plurality of depressions or pressions being formed to permit the end of the shell to slide freely thereover while being inserted but acting as a hook to prevent its withdrawal. Fig. 6 is broken away on a section to one side of the battery cup. and shows the Wings 10 in elevation.

According to the modified form of the anchor shown in Fig. 7 the shell engaging projections are formed by stamping a plurality of disconnected annular depressions in the' outer cylindrical wall, said recesses being arranged preferably in two series so as to overlap in such a manner as to form an effective bafile entirely around the periphery of the cup-shaped anchor. In this embodiment, means for engaging the base wad are provided by the inwardly contracted hollow protuberances 18 which are open at their inner ends to permit portions of the wadding to be compressed thereinto and expanded therewithin to interlock therewith. In the modification shown in Fig. 8, the shell engaging protuberance is formed by a groove 19, which is stamped in the outer cylindrical wall of the anchor. In this modification, the wad-engaging means is provided by a pinrality of open-ended hollow protuberances 20 with star points opening laterally to grip the material of the base wad.

The advantageous features of my improved cartridge will now be appreciated from the following brief statement :--The cup-shaped reinforce or anchor is expanded around its peripheral corner within the annular flange or shoulder 3 of the cap, thereby securely locking the cap and anchor tog'ether. The base wad being in turn securely locked to the reinforce or anchor, is in consequence firmly secured to the cap 2, thereby making it practically impossible for it to be dislodged during the discharge of the gun. A further very important feature resides in the interlocking connection between the inner end of the tubular shell 1 and the outer cylindrical wall of the reinforce or anchor whi h prevents absolutely the separation, so co mon in devices of this kind, between the pa er shell and the cap. The outer cylind ical wall of the reinforce or anchor, of c urse, serves strongly to reinforce the inner end of the paper shell and effectually preyents, in the event of an imperfect fit between the shell and the-gun' bore, the cylindrical wall of the cap being expanded permitting a rupture of the paper shell. By

this means, therefore, the parts being seindentations 16, said de- The view shown incurcly held together in'their relative positions, the escape of'gases; is effectually prevented and all of the disadvantageous features attending the occurrence of a flare back or rupture of the shell are'obviated.
